I think it uses node.js. Or somehow other uses libv8.
I mentioned that I installed libv8 from ports so that you could provide
me with the secret handshake for make it all work together!
What I think you're saying is that bundle should just work ?

bundle tries to compile libv8 and fails because g++44, g++45, g++46 don't exist
(eg++
of course) which appear to be the debian/ubuntu names for explicit versions of
g++.
When I run gem by hand, it tries to compile libv8 with g++ and runs into
some error (that may be related to the fact that it isn't g++ 4.4 or higher.)
Building native extensions. This could take a while...
